MOSCOW, Sept 8 (Reuters) - Russia's No.2 lender VTB, struggling with losses, replaced its chief finance officer with ex-Lehman Brothers banker Herbert Moos and named a new Risk Department head on Tuesday.
The government pumped 180 billion roubles ($5.70 billion) of fresh capital into the state-controlled bank on Monday.
VTB is expected to post a loss this year having reported a worse-than-expected net loss of 20.5 billion roubles ($648.7 million) for the first quarter of 2009 as bad loans rose.
Investors, who eschew the stock in favour of Sberbank, another state owned bank steadied by a vast deposit base, said they did not expect dramatic changes at VTB, which has a riskier loan portfolio and is more exposed to the volatile domestic stock market.
"The bank is making losses, investors are disappointed so it is not a big surprise the heads are rolling. But this is chance for the bank to do the right things," Zinaida Psiola, portfolio manager at Clariden Leu, said.
"I will see how will the newcomers tackle the bad loans. And I would give a second chance to the bank with pleasure," she said.
Shares in VTB closed up 3.29 percent, in line with the broader market and underperforming Sberbank which finished up 5.6 percent. The MICEX index gained 3.41 percent, driven largely by the banking stocks.
Investors have become concerned that commodity price gains may have been exhausted, leading them to switch from oil and mining shares into other sectors. Sberbank has become a proxy for a predicted economic rebound while VTB has lagged its peer.
Sberbank has promised investors a small profit this year. VTB's larger rival is expected to post a 4.24 billion rouble ($134.9 million) profit for the second quarter when it reports on Thursday.
Moos, who had been at Lehman Brothers for 14 years before joining VTB in 2008, will take over from Nikolai Tsekhomsky.
Alexander Yastrib, a VTB senior vice president, will be the new head of Risk, replacing Evgeny Novikov, who will continue to work for VTB in a new position, the company said on Tuesday.
Moos is currently CEO of VTB Capital, the investment banking arm of VTB Group. His last position at Lehman had been chief financial officer, Asia-Pacific ex-Japan, and treasurer, Asia-Pacific. ($1=31.60 Rouble) (Reporting by Dmitry Sergeyev and Oksana Kobzeva; editing by Elaine Hardcastle)
